What does sourcing and sinking of an LED mean?
What does sourcing and sinking of an LED mean?
Sink and Source are terms used to define the flow of direct current in an electric circuit. A sinking input or output circuit provides a path to ground for the electric load. A sourcing input or output provides the voltage source for the electric load.
What is the difference between sourcing and sinking?
Sinking and Sourcing are terms used to define the control of direct current flow in a load. A sinking digital I/O (input/output) provides a grounded connection to the load, whereas a sourcing digital I/O provides a voltage source to the load. A sinking digital I/O provides the ground needed in the circuit.
What is the difference between current sourcing and current sinking when leds are connected to the MCU?
So Current sourcing: It refers to the current required by a pin the microcontroller to drive an external load. Current Sinking: It refers to the maximum current that a pin can absorb through a load connected to an external supply. This will help you out in understanding more.
What is current sourcing and current sinking action?
Current sourcing and sinking refers to the way that an external load is connected to a circuit, system, microcontroller or other electronic device.
What is the difference between a source and a sink in a plant?
The key difference between source and sink in plants is that source in plants is the site of food production using biological processes while sink in plants is the site of food storage for later use. Whereas, the sites such as stems and roots which store the produced food are the sinks of the plant.
What is difference between current sourcing and current sinking in TTL logic?
The difference between current sourcing and current sinking is as follows: In the current-sinking process that occurs in the logic-0 state, the output transistor acts as a sink for other gates driven by it. The maximum value of the sinking current of a TTL NAND gate is 16 mA.
Is NPN sinking or sourcing?
PNP sensors are sometimes called “sourcing sensors” because they source positive power to the output. NPN sensors are sometime called “sinking sensors” because they sink ground to the output.
Is TTL sinking or sourcing?
Like DTL, TTL is a current-sinking logic since a current must be drawn from inputs to bring them to a logic 0 voltage level. The driving stage must absorb up to 1.6 mA from a standard TTL input while not allowing the voltage to rise to more than 0.4 volts.
